<br /> . <br /> E. Topography <br /> Generally, the topography of the corridor can be characterized as a shallow <br /> valley with a relatively broad flood plain. The flood plain (elevation 870-880) <br /> with intermittent oxbows is bordered by short embankments (8% - 12%), <br /> gently rolling plateaus (elevation 890) and steep sided (10% - 30%) knolls <br /> (elevation 900) and ridges (elevation 910). Refer to maps on pages VI-26 <br /> through VI-28 . <br /> F. Climate <br /> The seasonal variations in climate are conducive to a year-round variety of <br /> outdoor recreation activities, including the six activity types integral to a <br /> regional park. <br /> Reaional Climate <br /> Average number of days/year below OOF. 15 <br /> Average number of days/year above 900F. 6 <br /> Mean January minimum temperature 30 <br /> Mean January maximum temperature 210 <br /> Mean July minimum temperature 610 <br /> Mean July maximum temperature 820 . <br /> Annual average snowfall 42.2" <br /> Annual average total precipitation 24.7" <br /> Prevailing wind direction/winter NW <br /> Prevailing wind direction/summer S/SE <br /> Average length of season with recreationally I <br /> sufficient snowbase 100 days <br /> G. Man-Made Features <br /> 1. Shoreview Segment - refer to map on page VI-29. <br /> a. Aquaduct - two 60-inch diameter conduits parallel the north side of <br /> County Road I passing along the southern edge of the Shoreview <br /> segment. The St. Paul Water Utility pumps water extracted from the <br /> Mississippi River at Fridley to Charles Lake in North Oaks. <br /> b. Overhead Electric Transmission Line - an overhead electric <br /> transmission line (34.5 KV) passes through the Shoreview segment <br /> following the north-south extended alignment of Schutta Road, then <br /> westward across Rice Creek and along the northern edge of the <br /> Minnesota Highway Department materials storage area. Northern <br /> States Power Company periodically clears the easement of trees <br /> that threaten interference with the power lines. Due to its location, <br /> the transmission line is a moderate visual intrusion. <br /> . <br /> VI-22 <br /> ---- <br />
